Lord Siva says to his wife Parvati-devi: “O Mahadevi! Look! In Kali-yuga there is no easier way to eradicate sins than by the holy names of Lord Krsna. It is therefore essential to propagate the chanting of the Hare Krsna maha-mantra among the general populous. The people in Kali-yuga can be easily liberated from the greatest hell by performing sankirtana of this Hare Krsna maha-mantra. To chant the maha-mantra, first chant hare krsna twice, then chant krsna twice, then hare twice. After that, chant hare rama twice, then rama twice and again hare twice. Thus the maha-mantra: Hare Krishna Hare Krishna Krishna Krishna Hare Hare, Hare Rama Rama Rama Rama Rama Hare Hare. One should chant, articulate and perform sankirtana etc., of this Hare Krsna maha-mantra, which destroys all sins.”

“In this dark age of Kali-yuga, sincere devotees of the Supreme Lord Krsna should leave aside all other means for liberation and take full shelter of the holy name. This is their real responsibility and duty. There is unlimited bliss in chanting the different names of Krsna: Hari, Kesava, Govinda, Vasudeva and Jaganmaya. For one who chants constantly with unflinching faith, he remains unaffected by the reverses of Kali-yuga, because his heart has become purified by chanting.”

“Those who engage in chanting the holy name of Lord Hari (japa), are addicted to congregational chanting (kirtana) and engage in the worship of Lord Hari, have accomplished their desires in the age of Kali.”

“Whatever is achieved in Satya-yuga by meditation, in Treta by offering ritual sacrifices and in Dvapara by temple worship is achieved in Kali-yuga by chanting the names of Lord Kesava congregationally.”

“Whoever continuously chants Lord Krsna’s holy name, even in his sleep, can easily realise that the name is a direct manifestation of Krsna Himself, in spite of the influences of Kali-yuga. This has been ordained by Lord Krsna.

“In our normal activities of eating, sleeping, sitting, dreaming, etc. to chant Krsna’s names, while nullify the ill effects of Kali-yuga, is the perfection of speech. Even it a person chants Krsna’s names indifferently, he will surely achieve his svarupa, or original spiritual self and attain that state beyond all material fear and lamentation. He will reach Vaikuntha, the supreme goal.

Whatever result was obtained in Satya-yuga be meditating on Visnu, in Treta-yuga by performing sacrifices and in Dvapara-yuga by serving the Lord’s feet can be obtained in Kali-yuga simply by chanting the Hare Krishna maha-mantra.

Lord Brahma instructs his son and disciple, Narada Muni as follows: “The sixteen words of the Hare Krsna maha-mantra – (Hare Krsna Hare Krsna Krsna Krsna Hare Hare Hare Rama Hare Rama Rama Rama Hare Hare) – are especially meant for counteracting the sins of Kali-yuga. To save oneself from the contamination of Kali-yuga there is no other alternative, but to chant the Hare Krsna maha-mantra.After searching through all the Vedic scriptures one cannot find a method of religion for this age (Kali-yuga) so sublime as the chanting of the Hare Krsna maha-mantra.”

“’Hare Krsna Hare Krsna Krsna Krsna Hare Hare Hare Rama Hare Rama Rama Rama Hare Hare’ – This sixteen-name, thirty-two syllable mantra is the maha-mantra in Kali-yuga by which all living beings can be delivered. One should never abandon chanting this maha-mantra and take to other so-called purificatory processes which are practiced by rascals, or engage in chanting other metrical compositions of the name of Krishna that are against the pure conclusions of the scriptures, or are filled with rasaabhaas. About this divinely spiritual maha-mantra, which delivers one from material existence, the original guru, Lord Brahma, has said, kali-santararadi sruti, “The srutis have declared this mantra to be the best means of deliverance in the age of Kali”. Having all heard this from Brahma, the sons and disciples of Brahma, beginning with Narada, all accepted the Hare Krishna maha-mantra and, having meditated on it, attained perfection.

Sri Vedavyasa said to Romaharsana Suta “O my son the embodied soul who takes up the maha-mantra will become filled with transcendence, and by accepting it, even a drunkard will attain all perfections. I will recite this mantra to you, for you are a swan-like maha-bhagavata and a suitable candidate. Just see! The sixteen word maha-mantra, ’Hare Krsna Hare Krsna Krsna Krsna Hare Hare Hare Rama Hare Rama Rama Rama Hare Hare’, can destroy the sins of the three worlds. The Vedas do not mention a method for achieving liberation from material bondage superior to the chanting of this maha-mantra.

“O Brahma, yuga after yuga I kindly appear in many thousands of incarnations.” “Walking either on the path of arrows or the path of the Vedas, I deliver the devotees, destroy their enemies, and place My glory on the earth.” “For they who have become blinded by Kali-yuga, a mantra with My holy names will rise like a glorious sun. This verse is: Hare Krsna Hare Krsna Krsna Krsna Hare Hare Hare Rama Hare Rama Rama Rama Hare Hare.” “One should chant this mantra once, twice, thrice, as many times as one is able, or again and again for as long as one lives. By chanting this maha-mantra even a dogeater may become My devotee.”

(Vayu-Purana)

Pipplada mentions that Vrsabhanu Maharaja once prayed to Kratu Muni, “O Lord, if you want to favour me, then please donate to me the names of Hari.” At that moment the saintly Kratu Muni gave him the sixteen name maha-mantra (Hare Krsna Hare Krsna Krsna Krsna Hare Hare Hare Rama Hare Rama Rama Rama Hare Hare). By clearly pronouncing this maha-mantra, one can attain brahma (salokya, samipya, sarupya and sayujya). Not only that, one can attain krsna-prema, the fifth goal of human life (panca purusartha).’ ”

(Brahmanda Purana, Uttara Khanda 6.55)

Lord Brahma tells his son Pipplada as follows:

mantro guhyah paramo bhakti vedyah

“The Maha-Mantra is confidential, transcendental and can be understood only by devotional service, (bhakti-yoga).”

These sixteen names are supremely beautified. Those who chant them regularly are sober persons who are able to cross beyond the illusory energy. There is no other means. One should repeat this maha-mantra which is the supreme secret, regularly.

“Anyone who dances in front of Sri Hari and loudly chants the maha-mantra (Hare Krsna Hare Krsna Krsna Krsna Hare Hare Hare Rama Hare Rama Rama Rama Hare Hare) will destroy all witches of sin. Just as the water of sacred rivers like the Ganga purify the universe, similarly those who circumambulate Sri Hari and loudly perform nama sankirtana of the sixteen word maha-mantra with sweet voices and while clapping the hands, purify the entire universe.”

Chanting the peerless taraka-brahma-mantra (Hare Krsna Hare Krsna Krsna Krsna Hare Hare / Hare Rama Hare Rama Rama Rama Hare Hare), which is taraka-brahma-nama, the great chanting for deliverance in Kali-yuga, one obtains perfection. This is the truth. This is the truth. It is only by chanting this great mantra Lord Siva killed the Tripurasuras.

“‘Hare Krishna Hare Krishna Krishna Krishna Hare Hare, Hare Rama RamaRama Rama Rama Hare Hare’ — This sixteen-name, thirty-two syllable mantrais the maha-mantra in the age of Kali by which all living beings can bedelivered. One should never abandon chanting this maha-mantra and take toother so-called purificatory processes which are practiced by rascals, orengage in chanting other metrical compositions of the name of Krishna thatare against the pure conclusions of the scriptures, or are filled with rasabhasa.
About this divinely spiritual maha-mantra, which delivers one from materialexistence, the original guru, Lord Brahma, has said, kali-santararadi srutite, ‘Thesrutis have declared this mantra to be the best means of deliverance in the ageof Kali’. Having all heard this from Brahma, the sons and disciples of Brahma,beginning with Narada, all accepted the Hare Krishna maha-mantra and,having meditated on it, attained perfection.”

“Everything is accomplished by Hari-nama sankirtana, including the goal of life (sadhya) and the means for its attainment (sadhana). In this age of Kali, the only means for deliverance is the chanting of the names of Hari. There is no other way, there is no other way, there is no other way. ‘Hare Krishna Hare Krishna Krishna Krishna Hare Hare, Hare Rama Hare Rama Rama Rama Hare Hare.’ This verse of names is called the maha-mantra. It contains sixteen names of the Lord, consisting of thirty-two syllables. Chanting this mantra again and again will awaken the sprout of prema within the heart, and thus the goal of life and the means for its attainment is understood.”

(Sri Caitanya Bhagavata 1.14.143-147)

Gopala Guru Gosvami, drawing from the Brahmanda Purana has presented the following meaning for the maha-mantra:

“The Lord is known as Hari because he takes away the ignorance of his devotees by revealing to them the actual nature of the Supreme Lord and his personal spiritual form.

Because She steals Krishna’s mind, because She is the incarnation of Krishna’s joy, Radha is also known by the name Hara.

The dark, lotus-eyed lord, the only master of the highest joy, who brings pleasure to Gokula, the son of Nanda, is known as Krishna.

Krishna is also known as Rama because the joys of conjugal life are the essence of his being, because He is the titulary deity of loving sports incarnate, and because he brings pleasure to Srimati Radharani.”
